| Section2 = }} Tetrahedrane is a platonic hydrocarbon with chemical formula and a tetrahedral structure. Extreme angle strain (carbon bond angles deviate considerably from the tetrahedral bond angle of 109.5°) prevents this molecule from forming naturally. ==Organic tetrahedranes== In 1978, Günther Maier prepared a stable tetrahedrane derivative with four ''tert''-butyl substituents. These substituents are very bulky, and completely envelop the tetrahedrane core. Maier suggested that bonds in the core are prevented from breaking because this would force the substituents closer together (corset effect) resulting in Van der Waals strain. Tetrahedrane is one of the possible platonic hydrocarbons and has the IUPAC name tricyclo()butane. Unsubstituted tetrahedrane (C4H4) remains elusive, although it is predicted to be kinetically stable. One strategy that has been explored (but thus far failed) is reaction of propene with atomic carbon.〔''Tetrahedrane—Dossier of an Unknown'' Adelina Nemirowski, Hans Peter Reisenauer, and Peter R. Schreiner Chem. Eur. J. 2006, 12, 7411 – 7420 〕 Locking away a tetrahedrane molecule inside a fullerene has only been attempted in silico.〔''Endohedral complex of fullerene C60 with tetrahedrane, C4H4@C60'' Xiao-Yuan Ren a, Cai-Ying Jiang a, Jiang Wanga, Zi-Yang Liu Journal of Molecular Graphics and Modelling 27 (2008) 558–562 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tetrahedrane」の詳細全文を読む スポンサード リンク
